e2e: use io-timeout conditionally based on kernel version

Browse Source 
We need
https://www.mail-archive.com/linux-block@vger.kernel.org/msg38060.html
inorder to use `--io-timeout=0`. This patch is part of kernel 5.4

Since minikube doesn't have a v5.4 kernel yet, lets use io-timeout value
conditionally based on kernel version at our e2e.
